Jezki and Mount Benbulben proved spectacular winners of the supporting Grade 1 events on Day One of the Punchestown Festival.

Now unbeaten in four starts under Barry Geraghty, Jezki resoundingly turned around Cheltenham form with Champagne Fever in the Herald Champion Novice Hurdle while Mount Benbulben demolished his rivals in the Growise Champion Novice Chase, sparking a double for trainer Gordon Elliott.

The Jessica Harrington-trained Jezki tracked an apparently below par Champagne Fever until quickening into the lead on the approach to the final flight before stretching clear to triumph by 16 lengths.

“We let the horse do the talking,” said Harrington.

“I don’t know what made the difference from Cheltenham, but he was very good today. He took a chance at the second but, otherwise, jumped well. And he settled well for Barry (Geraghty).”

Uncertain about plans for next season, she added: “I must speak to J P (McManus) and Frank (Berry), but I imagine he’ll stay hurdling, over two miles next year.”

Always tanking, Mount Benbulben produced a near perfect round of jumping before slamming Tofino Bay by 22 lengths.

Winning trainer Gordon Elliott declared: “We always knew he was a good horse. But he had to get his jumping together. We’ve done a lot of work, schooling him, and he was down in Con Power’s yesterday.

“He’s had his critics. But I can tell you, he has a serious engine. He has to go right-handed. Going left would be a no-brainer. We have no plans in place yet for next year. We’ll just enjoy today.”

Elliott, who came close to winning the Goffs Land Rover Bumper with Wrath Of Titans, completed his double when the Gigginstown-owned Very Wood won the Finlay Motor Group Flat Race, giving Jane Mangan her first win as a 5lb claimer.
